, a specification.

'this invention relates to ear stakes and especially to such stakes as are for use on ears for hauling logs.

The objeets ot my invention are to provide. a stake which will be permanently mounted on the car; which can be easily re leased troni its operative position; which can be easily and quickly placed into opera tive position; which can be operatedfrom the opposite side ot' the car; in which a series of stakes on a side may-be simultaneously released or any one et them separately released; and in which the released stake is withdrawn into the supportinti, ybunk and does not protrude therefrom to catch in any structure forming,` part of the log-dump or in any way interterewith the free operation of the train. y

Further objects are' to improve the forni of the bunk on which the logs rest; and to i provide a stake and bunk which may be used on a logging' truck. A

l attain' these and .other objects by the devices, mechanisms, and arrangements illustrated in the accompanying drawings, in

Similar numerals of reference 'refe-r to similar parts throughout the several views.

The vear deck l is supported on suitable side sills 2 and intermediate sills 3 in the usual manner. At any number ot points in the ear deck, but preferably in tivo suitable points, .the deck l is removed entirely across the car and the bunks 4. are secured in place across the car on. the said sills 2 and 3. Each bunk el is made of metal and is hollow being` shaped like an inverted U, hav-- in'g a curved or arched top en which the logs rest and having no bottom, and the stakes 5 are mounted in each end of the bunk and their controlling bars' extend across the ear within the hunk. Each hunk l has a slot or socket with vertical parallel Walls ateach end, in which the stakes 5 are mounted and operate. Each stake 5 is ina-de of metal and is formed with a part adapted to extend vertically up from the end of the bunk to `torni the stake proper, andA with a radius part- 7 (Fig. extending substantially eti o'tl the radius part 7, said pivot'pin 9 beingthe center of the circle of 4vthe part 8. The part 8 is forked at :its end to receive'the har 10 which extendstheretrom across the car, Within the bunk, at a slightangle so as to pass to one side of the stake 5 at the other end ot the bunk. v The bunk 4: has a hole. ,il in its end Wall, to one side of the sta-lie slot, at each end, thronghjwhieh hole the end of the bar lO passes, and said bar has a notch 1Q in its lower edge near its end and a second notch similarlypesitioned hut ilarther from the end thereof, both of said notches bein-g adapted to lit over the.v Wall j -k bar lO'jnst extends a short vdistance through.

the hole l1 and the outermost notch 12 isin engagement with the wall. of the bunk through which the hole has been made, (right-hand end of Fig. 2) while-if the stake is in its withdrawn position the bal extends farther through the hole and the other notch 32 is in engagement with the said part (lett-hand end ot Fig. 2). The' positions, sizes, and proportions oi' the parts are such that when the stake is released' the vertical part. thereof is withdrawn 'into a horizontal position anddoes not extend substantially beyond the end of the bunk.

.It evident that it' a stake 4is to he rcleased all that is necessary to do isto raise the end ot its har so as to remove the vvnotch l), out of. contact with the wall and the sta-kc will immediately turn on its pivot pin 9 and drop, forcing the -bar l() farther out of the hole 11- until the inner `notch 32 thereon catches on the wall and holds the stake in the withdrawn position. bar 10 may he raise d\to release the stake by a hand bar 13 (Fig) Vwhich rests on a lug 14 formed on the end of the bunk 4 and which engages under the said bar 10. 'IA releasing meeaani'srn is also provided whereby all the stakes on one side of the carmay bev siniultaiineously released (Figs. '4,5 and 6).

This consists ot-alever 15 pivotedto the. -bunk adjacent to each bar, ata.' point between the sides-ill 2 and the adjacent intermediate sill 3, in such posltwn and ot such shape that a portion thereof will engage under the lower sideof the bar to raise the har in the hole when the saidlever 15 is actuated. All of these levers 15am attached -bar 19, its inner end is raised-thus raising the extension 1 7 and all of thev levers l5 and simultaneously allowing all of the stakes 5 on the-other side ofthe ear to be released.

Referring now to ltiigst), 10 and 11': I' have here shown the bunk 24 provided with a vertical centr l flange 26,'and-the stakes 25 provided wit :i similar flanges 28 extending inward .therefrom all said llangesQG and 28 being adapted to sink into the bark ofthe logs to firmly attach the logs to the'bunk and prevent any endwise motion 'thereof thereon and thus to'v tasten the logging trucks at each endoit-the logs together.

The bunks 24 are provided with centralking-pins 2 engaging the crossbeain of the truck in the usual manner. The other parts The end of the inf/2,516

i ot this logging truck bunk and stakes aren similarto those already described.
